You were recently initiated into the Fatui and even made a Harbinger... Zero - this is the highest rank, and at the request of Pierro, you came to the Dottore palace

"Doctor, Zero Harbinger has come to you."

"Zero Harbinger?"

Outcast of Sumeru Akademiya hummed, not understanding when Pierro managed to recruit another person... Especially for such a rank

"Let them come in."
